HENRY KCHMANN, OF HOBOKEN, NEW' JERSEY,

lHOTOGRAPHC-PLATE-HOLDER KIT.

Application filed May 24, 1924. Serial N'o. 715,646.

T 0 all whom, t may concer/n.'

Be it known that I, HENRY KUCHMANN, a citizen of the United States, residing at Hoboken, in the county of I-Iudson and State of New Jersey, have invented certain new and useful Improvements in Photographic- Plate-I-Iolder Kits, of which the following is a specification.

This invention relates to new and useful improvements in photographic plate holder kits for cameras, and has for its principal object to provide a simple and efficient means for holding a photographic plate in the kit, without having to adjust clamping members in order to hold the plate in position in the kit.

A further object of the invention is to provide a device of the above mentioned character, wherein considerable time and labor will be saved in placing the photographic plate and supporting the same in position in the kit and further preventing the accidental displacement of the plate from the kit.

A further object of the invention is to provide a device of the above mentioned character, which is simple in construction, inexpensive, strong and durable, and further well adapted for the purposes for which it is designated.

Other objects and advantages will become apparent during the course of the following description.

In the accompanying drawing,l forming a part of this specification, and in which like numerals designate like parts throughout the same:

Figure 1 is a front elevation of my improved kit,

Figure 2 is a rear elevation thereof,

Figure 3 is an end elevation, and

Figure 4 is a detail perspective view of the frame comprising my improved kit, with one of the end sections removed.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates generally the frame comprising the kit and the same includes the spaced side bars 2 and 3 respectively, which are connected together at one end by means of the end bar or section 4. The opposite end portions of the side bars 2 and 3 have the back faces thereof provided with cut-away portions 5 and 6 respectively, and the purpose of this construction is to provide a means for removably and adjustably supporting the eX- tensions 7 and 8 respective-ly, provided on the ends of the opposite end section 9. The front faces of the end sections 4 and 9 respectively are provided with the inwardly extending slips 10 and 11 respectively, and the same extend between the side bars 2 and 3, in a manner as is obvious from the construction shown in Figure 4. The purpose of this construction is to provide a means for permitting the forward movement or displacement of the photographic plate, which is supported in the frame, For the purpose of preventing the rearward movement of the plate, in the frame, the diagonally extending cross strips 12 are fastened to the back faces of the end sections 4 and the side bars 2 and 3, in the manner as more clearly illustrated in Figure 2 of the drawing. The back faces of the opposite ends of the side bars 2 and 3 have fastened there-` on the plate 13, by means of the fastening elements 14 and the plates are adapted to extend over the adjacent end portions of the opposite end section 9 and also the inner upper portion of each of the plates is disposed inwardly of the side bars and end section 9 for engagement with the opposite rear portion of the photographic plate supported in the frame.

It is to be understood, however, that the plates 13 are fastened on the back faces of the side bars 2 and 3 in such a manner as to not prevent or interfere with the sliding movement of the end section 9 with respect to the cut-away portions 5 and 6. The slidable end section 9 is adapted to cooperate in conjunction with the usual spring of the plate holder, and after the plate is put in position in the kit, it will be impossible for the same to fall out therefrom. A. kit of the above mentioned character will eliminate the time and labor which is lost in placing the plates in position in the kits now in use, and furthermore the necessity for small catches, for securing the plate in position in the kit is obviated.

The simplicity of my device enables the same to be manufactured at a very low cost, and it may be constructed of any suitable material, so as to render the same strong and durable.

Ihile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to, without departing from the spirit of the invention and the scope of the appended claim.

Having thus described my what is claimed is:

A plate holder kit for cameras in the form of a frame comprising a pair of spaced side bars, an end section connecting the side bars at one end thereof, the opposite ends of said side bars having the back portions thereof provided with notches, an additional end section disposed between the invention,

side bars adjacent the notches, lateral projections provided on the ends of the last mentioned end sections for slidable niovel HENRY KUCHMANN.
